A belt tensioner for a seat belt system includes a spur gear arrangement (18). The spur gear arrangement (18) comprises at least one motor gear (24) and at least a first cone pulley (26) and a second cone pulley (28). The motor gear (24) forms a first gear stage (34) with the first cone pulley (26) and the first cone pulley (26) forms a second gear stage (36) with the second cone pulley (28). Each of the motor gear (24) and the cone pulleys (24, 26) comprises helical teeth, and the helical angle of the helical teeth of the second gear stage (36) is determined as a function of the helical angle of the first gear stage (34). The overlap ratio of at least one helical tooth is not an integer.

    一种用于座椅安全带系统的安全带张紧器,该安全带张紧器包括正齿轮装置(18)。正齿轮装置(18)包括至少一个马达齿轮(24)和至少第一塔轮(26)和第二塔轮(28)。马达齿轮(24)与第一塔轮(26)形成第一齿轮级(34),并且第一塔轮(26)与第二塔轮(28)形成第二齿轮级(36)。马达齿轮(24)和塔轮(24,26)中的每个塔轮均包括螺旋齿,并且第二齿轮级(36)的螺旋齿的螺旋角根据第一齿轮级(34)的螺旋角来确定。至少一个螺旋齿的重叠率不是整数。
